Week in Rock: Siren to CMJ Edition

<strong>Kanye, Not Jay-Z, Makes Brief Webster Hall Appearance</strong><p>Hey, that's not Jay-Z! The rapper <a href="http://gothamist.com/2009/07/30/rumor_alert_jay-z_playing_webster_h.php">was rumored</a> to be a special guest at last night's Diesel party at Webster Hall, but the crowd got Kanye instead. And he only performed one song (with Clipse)! The rest of the night went on as planned, with not-so-surprise peformances by The Roots, Lykke Li, Terror Pigeon Dance Revolt (that band sounds terrifying!), Heartsrevolution, <a href="http://www.brooklynvegan.com/archives/2009/07/noisettes_playe.html#more">The Noisettes</a>, Theopholis London, Cobra Starship and Passion Pit. Word is that, unsurprisingly, The Roots stole the show. <a href="http://www.youtube.com/watch?v=uWkCK5LT6BY">Here's some video</a> from Kanye's performance; from the looks of it, higher quality stuff was being filmed and will hopefully find its way onto the internet.</p>
